Meaningless, IMHO. 24 hour could have been any irradiated zebra farting in the next state. Give it a couple weeks, minMy average is1.63 now. Slowly dropping. I don't know why the first 24 hrs was so high over 3.0
I would imagine if there are ANY irradiated Zebras running around loose in the States, we should definitely be on the watch for them.Meaningless, IMHO. 24 hour could have been any irradiated zebra farting in the next state. Give it a couple weeks, min
Sweet mother of remediation that's a serious radiation drop Batman!I recently had a mitigation system installed.
It's your typical system where a fan sucks the air from under the basement floor.
I did the short term (six day) test.
Results from 'independent tester' are:
Before .... 9.6
After ....... 0.7
I have two digital gages (sitting side-by-side),
for the last three weeks, my readings are below 1.0
After 30 days of getting daily readings, I may turn the fan OFF and see how long it takes for the reading to increase.
The installer told me if I turn the fan OFF, the readings may not go as high as they were originally.
The reason being - there is now a pvc vent-pipe going from under the floor to outside.
Depending on the pressure under the floor, some of the radon may vent itself (with the fan OFF).
What a great feeling that you got that taken care of, you must be thrilled.I turned radon fan OFF and next day l saw the gage readings go up.
These are the numbers using an Airthing digital gage.
8.0 - 10.0 .... before fan installation
0.9 .................. after fan installed and running
7.0 - 8.0 ....... fan OFF using pvc as natural vent (lower readings, but still to high)
0.9 ................. fan turned back ON
